APPLICATION OF OZON GENERATORS IN APICULTURE DURING THE SPRING BUILD-ING-UP OF BEE FAMILIES
DescriptionIn the article we have represented the following items: the sphere of utilization of the ozone in apiculture, the mathematical model which establishes connection between level of development of bee families and parameters of in-hive microclimate and allows to theoretically substantiate the spring development up to 35 % as a result of ozone treatment; the results of experimental investigations of the influence of ozone treatment parameters on the spring increasing of bee families; feasibility study of ozone generators' application in apiculture; recommendation for application of the results of investigation are given

Description
In the article we have represented the following items: heating model of discharge device of the ozone gen-erator which allows to examine the transient process and establishes dependence of heating time constant of the dielectric barriers on constructive parameters of discharge device. The rational parameters of design of the ozone generator for in-hive treatment of the bee families are defined; recommendations for utilization of the results of investigations are given

PROTEIN-CHITOSAN COMPLEX IN GLAZED CURD TECHNOLOGY
DescriptionResults of rheological investigations of protein-chitosan complex obtained from milk-whey system with different ratio of components are demon-strated. Portable consistometer to determine elastic behavior of the samples is designed. Optimal protein-chitosan complex, close in rheological parameters to curd cheese 18% fat, is detected

Description
The article describes the results of experimental researches of receiving fullerene soot in plasma of impulsing discharge. Receiving the soot of fullerene occurred at fuel oil decomposition. From features of experimental conditions, it is possible to specify that synthesis of fullerene nanocarbon soot occurred at atmospheric pressure. The analysis of the received samples of a fullerene soot was made by a mass spectrometry method with a laser desorption (MALDI). For the purpose of increase of efficiency of plasma chemical synthesis the cathode is executed in the form of a hollow can with a permeable bottom wall through which giving of a hydrocarbon material was made

The possibility of reducing dynamic loads on the driving elements of hydraulic manipulator with a combination of motions of the three links is theoretically justified and confirmed by tests
-
Description
In the article, we theoretically determined system of equations, describing the motion of hydro manipulator elements without compressibility, ductility and energy dissipation
